Abstract
An improved pre-matched active modulated tuner is used for hybrid load pull testing microwave transistors subject to modulated signal stimulus. A modulation pattern correction method uses calibration data of a pre-matching passive slide screw tuner to modify the data management of the numeric processor of the active tuner and allows lower power requirement of the active tuner and precise target tuning using optimization with a realistic starting point.
